Mortality risk associated with combinations of loneliness and social isolation. Findings from The Irish Longitudinal Study on Ageing (TILDA)

The unique and synergistic effects of social isolation and loneliness on 20-years mortality risks in older men and women

Introduction

This study investigates the individual and combined impacts of loneliness and social isolation on 20-year mortality risks among older men and women.

Methods

Utilizing data from the Norwegian Life Course, Ageing, and Generation study (NorLAG) carried out in 2002, 2007 and 2017, we assessed loneliness via direct and indirect questions, and social isolation through factors like partnership status and contact frequency with family and friends. Yearly information on mortality was derived from the national registries and was available until November 2022. Gender-stratified Cox regression models adjusted for age and other risk factors were employed.

Results

Of the 11,028 unique respondents, 9,952 participants were included in the study sample, 1,008 (19.8%) women and 1,295 (26.6%) men died. In the fully adjusted models including indirectly assessed loneliness, social isolation increased the 20-year mortality risk by 16% (HR = 1.16, 95% CI 1.09-1.24) for women and 15% (HR = 1.15, 95% CI 1.09-1.21) for men. This effect was primarily driven by the absence of a partner and little contact with children for both genders. Loneliness measured with indirect questions lost its significant association with mortality after adjusting for social isolation and other factors in both genders. However, for men, reporting loneliness via a direct question was associated with a higher mortality risk, even in the fully controlled models (HR = 1.20, 96% CI 1.06-1.36). Interactions between loneliness and social isolation were not, or only borderline significantly, associated with mortality risks in the fully controlled models.

Discussion

Social isolation, but not loneliness measured with indirect questions are associated with a 15-16% higher mortality risk in both men and women. However, loneliness assessed with a direct question is associated with increased mortality in men, even after controlling for social isolation and other relevant factors, which might suggest that men may deny loneliness, unless it is (very) severe. These findings emphasize the importance of methodological precision in the measurement of loneliness and social isolation.

Factors associated with loneliness, depression, and anxiety during the early stages of the COVID-19 pandemic

The COVID-19 pandemic was an unparalleled stressor that enhanced isolation. Loneliness has been identified as an epidemic by the US Surgeon General. This study aimed to: (1) characterize longitudinal trajectories of loneliness during the acute phase of the COVID-19 pandemic; (2) identify longitudinal mediators of the relationship of loneliness with anxiety and depression; and (3) examine how loneliness naturally clusters and identify factors associated with high loneliness. Two hundred and twenty-nine adults (78% female; mean age = 39.5 ± 13.8) completed an abbreviated version of the UCLA Loneliness Scale, Perceived Stress Scale, Emotion Regulation Questionnaire, State Anxiety Inventory, and Patient Health Questionnaire-8 longitudinally between April 2020 and 2021. Trajectory analyses demonstrated relatively stable loneliness over time, while anxiety and depression symptoms declined. Longitudinal analyses indicated that loneliness effects on anxiety and depression were both partially mediated by perceived stress, while emotion regulation capacity only mediated effects on anxiety. Three stable clusters of loneliness trajectories emerged (high, moderate, and low). The odds of moderate or high loneliness cluster membership were positively associated with higher perceived stress and negatively associated with greater cognitive reappraisal use. Our results demonstrate the important interconnections between loneliness and facets of mental health throughout the early phases of the pandemic and may inform targeted future interventions for loneliness work.

Association of social health with all-cause mortality and cause-specific mortality: A population-based cohort study

BACKGROUND

Previous studies only focused on the individual social factors, without considering the overall social health patterns. The present study aimed to develop an integrated social health score (SHS) and investigate its associations with all-cause, cardiovascular disease (CVD), cancer mortality.

METHODS

A total of 330,716 participants (mean age 56.3 years; 52.4 % female) from UK Biobank was included between 2006 and 2010, and thereafter followed up to 2021. SHS was calculated by using information on social connections, social engagement and social support. Cox proportional hazards models was used to estimate the hazard ratios and 95 % confidence intervals (CIs) of the association between SHS and all-cause and cause-specific mortality and the 4-way decomposition was used to quantify the mediating effect of lifestyle factors.

RESULTS

During a median follow-up period of 12.4 years, 37,897 death cases were recorded, including 4347 CVD and 10,380 cancer cases. The SHS was inversely associated with the risks of all-cause, CVD and cancer mortality in a dose-dependent manner (P for trend <0.001). The association between SHS with all-cause mortality was mediated by lifestyle factors including diet score, smoking status and alcohol consumption.

CONCLUSION

Integrated SHS was inversely associated with risks of all-cause, CVD and cancer mortality, and the associations were partially mediated by lifestyle factors. Our study highlights the importance of maintaining high levels of social health by jointly enhancing social involvement, expanding social networks, and cultivating enduring intimate relationships across the life course.

Prevalence and determinants of loneliness among the oldest old living in institutionalized settings : Study findings from a representative survey

BACKGROUND

There is very limited knowledge regarding the prevalence and determinants of loneliness in oldest old residents of nursing or old age homes.

OBJECTIVE

To examine the prevalence and determinants of loneliness among the oldest old living in institutionalized settings in Germany.

MATERIAL AND METHODS

Data were taken from the representative survey on quality of life and subjective well-being of the very old in North Rhine-Westphalia (NRW80+) including individuals ≥ 80 years living in North Rhine-Westphalia. The study focused on individuals living in institutionalized settings. Sociodemographic, lifestyle-related, and health-related determinants were included in multiple linear regression models.

RESULTS

Approximately 56.6% of the individuals were not lonely, 25.7% and 17.8% of the individuals were moderately and severely lonely, respectively. Regression analyses showed that higher loneliness was associated with being married (β = 0.48, p < 0.05), high education (compared to low education, β = 0.46, p < 0.05), having a small social network size (β = -0.02, p < 0.05), having poor self-rated health (β = -0.25, p < 0.05), and more depressive symptoms (β = 0.25, p < 0.001).

CONCLUSION

A significant proportion of the institutionalized oldest old individuals reported moderate or severe loneliness, which underpins the relevance of this topic. Understanding the determinants of loneliness may help to address institutionalized adults aged 80 years and over at risk of loneliness.

Predictive factors and risk and protection groups for loneliness in older adults: a population-based study

BACKGROUND

Loneliness is considered a public health problem, particularly among older adults. Although risk factors for loneliness have been studied extensively, fewer studies have focused on the protected and risk groups that these factors configure. Our objective is to analyze the variables and latent factors that predict loneliness in older adults and that enable risk and protected groups to be configured.

METHODS

We employed an epidemiological, cross-sectional survey that was carried out on a random sample of 2060 people over 65 years extracted from the census. A structured telephone interview was used to assess mental and physical health, habits, quality of life, and loneliness, applying the COOP-Wonca, Goldberg General Health (GHQ-12), and Barber Questionnaires.

RESULTS

Predictors of loneliness were: mental health, living alone, quality of life, depressive symptoms, low educational level, and some deficiency situations such as having no one to turn to for help. The factors extracted (Factorial Analysis) were: a subjective experience of poor health, objective isolation, and psychological isolation. We established at risk and protected groups ("Decision Tree" procedure), and loneliness was referred to by 73.2% of the people living alone and with poor mental health and quality of life (risk group). By contrast, only 0.8% of people living with others, with good mental health and good quality of life felt loneliness (protected group).

CONCLUSION

In a well-developed city, subjective and objective factors are associated with loneliness. These factors, especially those associated with at risk or protected groups, must be considered to develop strategies that address loneliness.

Social isolation and the risk of Parkinson disease in the UK biobank study

Parkinson disease (PD) has become one of the most rapidly growing causes of disability among the older population and social isolation is a major concern in the PD community. However, the relationship between social isolation and future risk of PD remains unclear. This study included 192,340 participants aged 60 or older who were free of dementia and PD at baseline from the UK Biobank study. Social isolation was measured using a composite score derived from three questions on number in household, frequency of friend/family visits, and leisure/social activities. Incident PD cases were identified through electronic health records. Multivariable-adjusted Cox regression models were used to compute the hazard ratio (HR) and 95% confidence interval (CI). Among the 192,340 participants (mean [standard deviation] age, 64.2 [2.9] years; 103,253 [53.7%] women), 89,075 (46.3%) participants were in the least isolated group and 26,161 (13.6%) were in the most isolated group. Over a median follow-up of 12.5 years, 2048 incident PD cases were documented. Compared to the least isolated group, the multivariable-adjusted HRs (95% CIs) for PD were 1.00 (0.91-1.10) for the moderately isolated group and 1.19 (1.05-1.36) for the most isolated group (P-trend = 0.04). The observed association was independent of the genetic susceptibility to PD and consistent in subgroup analyses. Social isolation was associated with a higher risk of PD regardless of genetic risk. Our findings highlighted the importance of developing screening and intervention strategies for social isolation among older adults to reduce the risk of PD.

Effect of empowerment: how and when do high-involvement work practices influence elder employees' innovative performance?

Introduction

In today's fast-paced business environment, innovation from elder employees is increasingly vital to organizations. High-involvement work practices that emphasize engagement and empowerment have a significant impact on the innovation performance of these employees, harnessing their wealth of experience and fostering organizational growth. However, most of the current research on innovation performance focuses on the single factor of the individual or the organization, and most of them focus on the linear relationship; research on the factor of human resource practices, in particular high-involvement work practices, is inadequate.

Methods

Based on social exchange theory, this paper uses structural equation modeling (SEM) to examine the impact of high-involvement work practices on elder workers' innovation performance using 278 valid samples from three time points, and the non-linear effects of exploratory and exploitative innovation on elder workers' innovation performance.

Results

(1) There is no significant relationship between high-involvement work practices and elder employees' innovation performance. (2) Exploratory innovation has a significant U-shaped relationship with innovation performance, i.e., as the level of exploratory innovation increases, the innovation performance of elder employees first decreases and then increases. There is a significant inverted U-shaped relationship between exploitative innovation and innovation performance, i.e., as the level of exploitative innovation increases, innovation performance first increases and then decreases. High-involvement work practices have a U-shaped effect on elder employees' innovation performance through exploitative innovation. (3) Transformational leadership moderates the direct effects of high-involvement on exploratory innovation and elder employees' innovation performance, and transformational leadership moderates the U-shaped effect of high-involvement work practices on elder employees' innovation performance through exploratory innovation.

Discussion

The conclusion is helpful for organizations to enhance elder employees' innovation performance by enriching high-involvement work practices.

Loneliness, Psychological Well-being, Depression, and Social Participation in the Older Persons: Rural and Urban Differences

INTRODUCTION

The purpose of this study is to compare the loneliness, psychological well- being, depression, and social participation of elderly people living in Turkish society between rural and urban areas. The sample group of the study, in which a correlational survey model was used, consisted of 610 elderly adults.

METHOD

The study population consists of two groups: the first group consists of individuals over 65 years of age living in the city (Istanbul) (n= 291), and the second group consists of individuals over 65 years of age living in rural areas (rural areas of Ordu) (n= 319). Socio-demographic Information Form, Loneliness in the Elderly Scale, Geriatric Depression Scale, Psychological Well-Being in the Elderly Scale, and Social Inclusion Scale were applied online. Statistical analyses of the study were conducted using SPSS 27.00, and the Independent Samples t-test and ANOVA test were used.

RESULTS

According to the findings of this study, statistically significant results were found in psychological well-being, social inclusion, social relations, loneliness and depression, and place of residence. It was observed that the social isolation and social acceptance levels of those living in urban areas were higher than those living in rural areas. Social, loneliness, and depression scores of those living in the village/town were found to be higher than those living in the city centre. Furthermore, the social relationship scores of those living in the village/town were found to be higher than those living in the city centre.

CONCLUSION

The increasing elderly population worldwide has become an issue that requires global measures. Place of residence is one of the factors thought to affect older people's health and well- being. It is thought that the study data will contribute to new policies that will ensure the protection and promotion of elderly health and those working in this field. In addition, the study, which provides information about Turkish culture, will also enable intercultural comparisons.

Frailty Knowledge, Use of Screening Tools, and Educational Challenges in Emergency Departments in Ireland: A Multisite Survey

BACKGROUND

Recognizing frailty and providing evidenced-based management in busy emergency departments is challenging. Understanding the knowledge and educational needs of ED staff is important to design training that might improve patient outcomes.

OBJECTIVE

This study aimed to explore frailty knowledge of ED staff, use of frailty screening instruments in Irish emergency departments, and educational challenges in the emergency department.

METHODS

A multisite survey of ED staff (different specialties) was conducted between April and September 2021. An anonymous online survey was distributed via email. Free-text sections were analyzed using content analysis.

RESULTS

In total, 168 staff (nursing, medical and allied health) participated, representing 9 of 26 Irish emergency departments (35%). Most respondents were nurses (n = 78, 46%). Less than half of respondents had received frailty identification training (n = 81, 48%). One-fifth of emergency doctors and nurses (20%) were unsure how to define frailty. Major barriers to ED frailty screening were resource deficits, insufficient diagnostic pathways from the emergency departments, and lack of education on suitable instruments.

CONCLUSIONS

Most of the ED staff surveyed relied on clinical judgment rather than formal training in frailty identification. A high proportion reported poor knowledge and low confidence in recognizing frailty. Dedicated staff with frailty management expertise, bespoke education initiatives, and clearly defined frailty screening pathways may help address the issues identified.

The effects of loneliness and social isolation on cognitive impairment-free life expectancy in older adults

OBJECTIVES

This article aimed to examine the effects of social connection comprising loneliness and social isolation on cognitive impairment-free life expectancy (CIFLE).

METHODS

Data on 28,563 older adults (aged 65+) were drawn from the Chinese Longitudinal Healthy Longevity Survey with a median follow-up of 4.00 years. Multistate Markov models were used to estimate the independent and joint effects of social connection with CIFLE. Cognitive impairment was measured by the modified Mini-Mental State Examination.

RESULTS

For men and women, respectively, reduced CIFLEs at age 65 associated with loneliness were 0.95 (95% CI: 0.41-1.48) and 1.35 (95%: CI 0.77-1.90) years, and those associated with social isolation were 2.23 (95% CI: 1.67-2.78) and 2.49 (95% CI: 1.67-3.30) years. Compared with those with neither loneliness nor social isolation ('neither' group), older adults at age 65 with both loneliness and social isolation ('both group') lost CIFLEs of 2.68 (95% CI: 1.89-3.48) and 3.51 (95% CI, 2.55-4.47) years for men and women, respectively. Similar patterns were observed in the oldest-old adults (age 85 or over). A growth trend transpired in the difference of the proportion of the remaining CIFLE between 'neither' group and 'both' group with age.

CONCLUSION

Loneliness and social isolation are associated with decreased CIFLE in older Chinese adults. Policy makers and the public must be informed that early identification and management of loneliness and social isolation, especially when coexisting, are crucial.

The effectiveness of facilitator-led remote interactive intervention for loneliness, quality of life, and social support among seniors in communities during the COVID-19 pandemic: a randomized controlled experiment

OBJECTIVE

This study investigated the impact of a 12-week remote interaction intervention on loneliness, quality of life, and social support for seniors living in a community during the COVID-19 pandemic.

METHODS

This study adopted a randomized controlled trial design. Participants in the intervention group received a 12-week bidirectional remote interaction intervention, while participants in the control group received a 12-week unidirectional remote interaction intervention. The study's primary assessment tools were the UCLA Loneliness Scale (UCLA) and the World Health Organization Quality of Life-BREF Scale (WHOQOL-BREF).

RESULTS

The main findings indicate that the intervention group scored significantly higher than the control group on the WHOQOL-BREF in the physical health and social relationships domains after the intervention. In addition, intervention group participants with low loneliness scored significantly higher than their control group counterparts in the physical health and social relationships domains of the WHOQOL-BREF. Similarly, intervention group participants with high loneliness scored significantly higher than their control group counterparts in the social relationships domain of the WHOQOL-BREF. However, there was no significant difference in loneliness scores between the intervention and control groups.

CONCLUSIONS

This result confirms that providing intensive bidirectional interaction benefits seniors' quality of life during the COVID-19 pandemic.

Social Withdrawal, Loneliness, and Health in Schizophrenia: Psychological and Neural Mechanisms

BACKGROUND AND HYPOTHESIS

Some of the most debilitating aspects of schizophrenia and other serious mental illnesses (SMI) are the impairments in social perception, motivation, and behavior that frequently accompany these conditions. These impairments may ultimately lead to chronic social disconnection (ie, social withdrawal, objective isolation, and perceived social isolation or loneliness), which may contribute to the poor cardiometabolic health and early mortality commonly observed in SMI. However, the psychological and neurobiological mechanisms underlying relationships between impairments in social perception and motivation and social isolation and loneliness in SMI remain incompletely understood.

STUDY DESIGN

A narrative, selective review of studies on social withdrawal, isolation, loneliness, and health in SMI.

STUDY RESULTS

We describe some of what is known and hypothesized about the psychological and neurobiological mechanisms of social disconnection in the general population, and how these mechanisms may contribute to social isolation and loneliness, and their consequences, in individuals with SMI.

CONCLUSIONS

A synthesis of evolutionary and cognitive theories with the "social homeostasis" model of social isolation and loneliness represents one testable framework for understanding the dynamic cognitive and biological correlates, as well as the health consequences, of social disconnection in SMI. The development of such an understanding may provide the basis for novel approaches for preventing or treating both functional disability and poor physical health that diminish the quality and length of life for many individuals with these conditions.

Are loneliness and social isolation equal threats to health and well-being? An outcome-wide longitudinal approach

The detrimental effects of loneliness and social isolation on health and well-being outcomes are well documented. In response, governments, corporations, and community-based organizations have begun leveraging tools to create interventions and policies aimed at reducing loneliness and social isolation at scale. However, these efforts are frequently hampered by a key knowledge gap: when attempting to improve specific health and well-being outcomes, decision-makers are often unsure whether to target loneliness, social isolation, or both. Filling this knowledge gap will inform the development and refinement of effective interventions. Using data from the Health and Retirement Study (13,752 participants (59% women and 41% men, mean [SD] age = 67 [10] years)), we examined how changes in loneliness and social isolation over a 4-year follow-up period (from t0:2008/2010 to t1:2012/2014) were associated with 32 indicators of physical-, behavioral-, and psychosocial-health outcomes 4-years later (t2:2016/2018). We used multiple logistic-, linear-, and generalized-linear regression models, and adjusted for sociodemographic, personality traits, pre-baseline levels of both exposures (loneliness and social isolation), and all outcomes (t0:2008/2010). We incorporated data from all participants into the overall estimate, regardless of whether their levels of loneliness and social isolation changed from the pre-baseline to baseline waves. After adjusting for a wide range of covariates, we observed that both loneliness and social isolation were associated with several physical health outcomes and health behaviors. However, social isolation was more predictive of mortality risk and loneliness was a stronger predictor of psychological outcomes. Loneliness and social isolation have independent effects on various health and well-being outcomes and thus constitute distinct targets for interventions aimed at improving population health and well-being.

A systematic review and meta-analysis of 90 cohort studies of social isolation, loneliness and mortality

The associations between social isolation, loneliness and the risk of mortality from all causes, cardiovascular disease (CVD) and cancer are controversial. We systematically reviewed prospective studies on the association between social isolation, loneliness and mortality outcomes in adults aged 18 years or older, as well as studies on these relationships in individuals with CVD or cancer, and conducted a meta-analysis. The study protocol was registered with PROSPERO (reg. no. CRD42022299959). A total of 90 prospective cohort studies including 2,205,199 individuals were included. Here we show that, in the general population, both social isolation and loneliness were significantly associated with an increased risk of all-cause mortality (pooled effect size for social isolation, 1.32; 95% confidence interval (CI), 1.26 to 1.39; P < 0.001; pooled effect size for loneliness, 1.14; 95% CI, 1.08 to 1.20; P < 0.001) and cancer mortality (pooled effect size for social isolation, 1.24; 95% CI, 1.19 to 1.28; P < 0.001; pooled effect size for loneliness, 1.09; 95% CI, 1.01 to 1.17; P = 0.030). Social isolation also increased the risk of CVD mortality (1.34; 95% CI, 1.25 to 1.44; P < 0.001). There was an increased risk of all-cause mortality in socially isolated individuals with CVD (1.28; 95% CI, 1.10 to 1.48; P = 0.001) or breast cancer (1.51; 95% CI, 1.34 to 1.70; P < 0.001), and individuals with breast cancer had a higher cancer-specific mortality owing to social isolation (1.33; 95% CI, 1.02 to 1.75; P = 0.038). Greater focus on social isolation and loneliness may help improve people's well-being and mortality risk.

Correlates of common concerns in older cancer survivors of leukemia and lymphoma: results from the WHI LILAC study

PURPOSE

Older survivors of leukemia and lymphoma often experience long-term effects of chemotherapy. We described common concerns related to their cancer and treatment in older survivors of leukemia and non-Hodgkin lymphoma (NHL) and assessed correlates of these concerns.

METHODS

We utilized data from the Women's Health Initiative (WHI) Life and Longevity After Cancer (LILAC) study that recruited post-menopausal women aged 50-79. Participants diagnosed with leukemia and NHL were included (n = 420). They were asked about 14 areas of current concerns related to their cancer and treatment and to rate each from 0 (no concern) to 2 (major concern), with total scores ranging from 0 to 28. Linear regression was used to assess factors correlated with the concern score, and logistic regression for factors correlated with the three most common concerns.

RESULTS

Mean age at assessment was 81 years (range 69-99); 72% reported at least one concern, and median concern score among these survivors was 3.5 (Q1-Q3 2-5). Factors significantly correlated with concern scores were sadness, pain, distress, higher prior symptom count, and loneliness (all p < 0.05). Significant factors correlated with common concerns were (1) fatigue/sleep: sadness/depression, distress, higher prior symptom count, greater loneliness, and worse physical functioning; (2) physical functioning/activity: older age, public insurance, higher body mass index, pain, worse QoL, and higher treatment-related comorbidities; (3) memory/concentration: prior chemotherapy or radiation, worse QoL, higher prior symptom count, and greater loneliness (all p < 0.05).

CONCLUSIONS AND IMPLICATIONS FOR CANCER SURVIVORS

Almost three-quarters of older survivors of leukemia and lymphoma reported at least one concern; a multifaceted intervention may be needed to address these concerns.

Social isolation, loneliness, and their correlates in older Japanese adults

BACKGROUND

Loneliness and social isolation are elevated in older adults and associated with a range of detrimental outcomes. Despite this, there has been little research on these phenomena or on similarities and differences in their occurrence or combination in older Japanese adults. The current study aims to (i) determine what factors are associated with social isolation and loneliness among older adults in Japan; and (ii) describe the characteristics of individuals who are socially isolated but not lonely, as well as those who feel lonely but are not socially isolated.

METHODS

Data were analysed from 13 766 adults aged ≥65 years who participated in the 2019 wave of the Japan Gerontological Evaluation Study. Poisson regression analysis was used to examine associations.

RESULTS

Among older Japanese adults, the attributes of higher age, male gender, lower socioeconomic status, being a welfare recipient, and having depressive symptoms were associated with social isolation, while lower socioeconomic status, unemployment, welfare receipt, and poor physical and mental health were associated with loneliness. In addition, better educated, and mentally and physically healthy people were less likely to feel lonely even when socially isolated, while people who were not working and who had mental or physical health problems were more likely to feel lonely even if they were not socially isolated.

DISCUSSION

Our results indicate that in order to reduce unwanted social isolation and loneliness among older Japanese adults, in the first instance the focus should be on those individuals who are socioeconomically disadvantaged and unhealthy.

Changes in mortality of Polish residents in the early and late old age due to main causes of death from 2000 to 2019

Purpose

The aim of the study was to assess mortality trends in Poland between 2000 and 2019 in the early and late old age population (65-74 years and over 75 years).

Methods

The work used data on all deaths of Polish residents aged over 65 years (N = 5,496,970). The analysis included the five most common major groups of causes of death: diseases of the circulatory system, malignant neoplasms, diseases of the respiratory system, diseases of the digestive system and external causes of mortality. The analysis of time trends has been carried out with the use of joinpoint models. The Annual Percentage Change (APC) for each segments of broken lines, the Average Annual Percentage Change (AAPC) for the whole study period (95% CI), and standardized death rates (SDRs) were calculated.

Results

The percentage of deaths due to diseases of the circulatory system decreased in all the studied subgroups. Among malignant neoplasms, lung and bronchus cancers accounted for the largest percentage of deaths, for which the SDRs among men decreased, while those among women increased. In the early old age, the SDR value increased from 67.8 to 76.3 (AAPC = 0.6%, p > 0.05), while in the late old age group it increased from 112.1 to 155.2 (AAPC = 1.8%, p < 0.05). Among men, there was an upward trend for prostate cancer (AAPC = 0.4% in the early old age group and AAPC = 0.6% in the late old age group, p > 0.05) and a downward trend for stomach cancer (AAPC -3.2 and -2.7%, respectively, p < 0.05). Stomach cancer also showed a decreasing trend among women (AAPC -3.2 and -3.6%, p < 0.05). SDRs due to influenza and pneumonia were increasing. Increasing trends in mortality due to diseases of the digestive system in women and men in the early old age group have been observed in recent years, due to alcoholic liver disease. Among the external causes of mortality in the late old age group, the most common ones were falls.

Conclusions

It is necessary to conduct further research that will allow to diagnose risk and health problems of the elderly subpopulation in order to meet the health burden of the aging society.

Sexual Orientation and Psychosocial Factors in Terms of Loneliness and Subjective Well-Being in Later Life

BACKGROUND AND OBJECTIVES

The aim of our study was to fill the gap in knowledge regarding the association between sexual orientation and psychosocial outcomes (loneliness and subjective well-being) based on nationally representative samples.

RESEARCH DESIGN AND METHODS

Cross-sectional data collected in 2017 were taken from a nationally representative sample of individuals in the second half of life (>40 years) in Germany (n = 4,785, average age 66.4 years, standard deviation [SD]: 10.5 years). Outcomes were assessed using well-established tools (life satisfaction: Satisfaction with Life Scale; positive and negative affect: Positive and Negative Affect Schedule; loneliness: De Jong Gierveld Loneliness Scale). Sexual orientation was dichotomized (heterosexual; sexual minorities including gay/lesbian, bisexual, and other). Analyses were adjusted for socioeconomic factors, lifestyle-related factors, and health-related factors.

RESULTS

In total, around 7.8% of respondents belonged to sexual minorities. Adjusted for various several socioeconomic, lifestyle-related and health-related covariates, linear regressions showed that sexual minority older adults reported higher loneliness scores (β = 0.07, p < .05), whereas sexual orientation was not associated with subjective well-being (life satisfaction, as well as positive and negative affect). Furthermore, our analysis showed that gender, age, marital status, and depressive symptoms were consistently associated with loneliness and subjective well-being.

DISCUSSION AND IMPLICATIONS

In accordance with minority stress theory, our study showed that sexual minority older adults report higher loneliness scores. This finding is important as loneliness has become widely acknowledged as a new geriatric giant, which could increase, for example, the risk of morbidity and mortality. Moreover, reducing loneliness is important for successful aging.

Association of loneliness and social isolation with all-cause mortality among older Mexican adults in the Mexican health and aging study: a retrospective observational study

BACKGROUND

Plenty of evidence shows how social isolation and loneliness are associated with increased risk for numerous diseases and mortality. But findings about their interactive or combined effects on health outcomes and mortality remains inconclusive.

OBJECTIVE

Analyze the longitudinal association of loneliness, social isolation and their interactions, with the all-cause mortality among older adults in Mexico.

METHODS

A retrospective observational study was conducted. Mexican adults older than 50 years were included. Data from the Mexican Health and Aging Study (MHAS) in the 2015 and 2018 waves were used. The subjects were classified according to their level of loneliness and the presence of social isolation. Multivariate logistic regression analyzes were performed to determine the degree of association between loneliness and social isolation with all-cause mortality at a 3-year follow-up.

RESULTS

From the total sample of 11,713 adults aged 50 years or over, 707 (6%) did not survive, 42% presented loneliness, and 53% were classified as socially isolated. After multivariate adjustment only social isolation (OR = 1.30, 95%CI:1.03-1.64) was associated with all-cause mortality, loneliness (Mild: OR = 0.83, 95%CI:0.59-1.16; Severe: OR = 1.03, 95%CI:0.71-1.64), and the interaction between loneliness and social isolation were not associated with all-cause mortality.

CONCLUSION

Social isolation, but not loneliness or their interaction, was associated with all-cause mortality in Mexican adults older than 50 years. This finding may help direct possible future interventions that help improve mental health in older adults from a highly collectivistic country.

Loneliness, Social Isolation, and Living Alone Associations With Mortality Risk in Individuals Living With Cardiovascular Disease: A Systematic Review, Meta-Analysis, and Meta-Regression

OBJECTIVE

This study aimed to conduct a systematic review and meta-analysis of associations between loneliness, social isolation, and living alone and risk of mortality among individuals with established cardiovascular disease.

METHODS

Five electronic databases were searched (MEDLINE [Ovid], PsycINFO, EMBASE, PubMed, and SCOPUS) from inception to November 25, 2021. In all, 35 studies were included in a narrative synthesis and, where appropriate, a meta-analytic evaluation using a random-effects model.

RESULTS

Living alone was associated with increased risk of all-cause mortality ( k = 15, n = 80,243, hazard ratio [HR] = 1.48, 95% confidence interval [CI] = 1.20-1.83, I2 = 83%), and meta-regressions found that the effects were stronger in studies from Europe and with longer follow-up. However, there was evidence of publication bias. Social isolation was associated with increased risk of all-cause mortality, measured both as a dichotomous variable ( k = 3, n = 2648, HR = 1.46, 95% CI = 1.08-2.04, I2 = 31%) and as a continuous variable ( k = 5, n = 2388, HR = 1.11, 95% CI = 1.02-1.24, I2 = 51%). Meta-analysis was not feasible for loneliness as exposure, but narrative synthesis of four studies suggested a tentative association between loneliness and increased risk of all-cause mortality.

CONCLUSIONS

Supporting public health concerns, our review finds that loneliness, social isolation, and living alone are associated with premature mortality among individuals with established cardiovascular disease. However, evidence of publication bias and large methodological differences across studies point to the need for more rigorous research.

Joint associations of social health and movement behaviours with mortality and cardiovascular disease: an analysis of 497,544 UK biobank participants

BACKGROUND

Poor physical activity and excessive sedentary behaviour are well-established risk factors for morbidity and mortality. In the presence of emerging social problems, including loneliness and social isolation, these risks may be even greater. We aimed to investigate the joint effects of social health and movement behaviours on mortality and cardiovascular disease (CVD).

METHODS

497,544 UK Biobank participants were followed for an average of 11 years. Loneliness and social isolation were measured via self-report. Physical activity was categorised around current World Health Organisation (WHO) guidelines as low (< 600 metabolic equivalent of task [MET]-mins/week), moderate (600 < 1200) and high (≥ 1200). Sedentary behaviour was classified as low (≤ 3.5 h/day), moderate (3.5 ≤ 5) and high (> 5.5). We derived 24 social health-movement behaviour combinations, accordingly. Mortality and hospitalisations were ascertained to May 2020 for all-cause and CVD mortality, and non-fatal cardiovascular events.

RESULTS

Social isolation amplified the risk of both all-cause and CVD death across all physical activity and sedentary levels (hazard ratio, 95% confidence interval [HR, 95% CIs] for all-cause mortality; 1.58 [1.49 to 1.68] for low active-isolated vs. 1.26 [1.22 to 1.30] for low active-not isolated). Loneliness was only found to amplify the risk of death from cardiovascular disease among the high active and low sedentary participants. Loneliness and social isolation did not add to the risk of non-fatal cardiovascular events across most activity levels.

CONCLUSION

The detrimental associations of poor physical activity and sedentary behaviour with mortality were consistently amplified by social isolation. Our study supports the need to target the socially isolated as a priority group in preventive public health strategies.

Hair cortisol as a risk marker for increased depressive symptoms among older adults during the COVID-19 pandemic

Determining pre-existing biological risk markers of incident depression and other mental health sequelae after exposure to a new stressor would help identify vulnerable individuals and mechanistic pathways. This study investigated primarily whether hair cortisol predicted elevated depressive symptoms in middle-aged and older adults during the COVID-19 pandemic, 6 years later. A secondary aim was to deduce whether any association differed by sex.

METHODS

We studied 1025 adults aged 50 and older (75% female) as part of The Irish Longitudinal Study on Ageing. Hair cortisol samples were collected at 2014 (Wave 3) and depressive symptoms were assessed using the 8-item Center for Epidemiological Studies Depression Scale in 2014 (Wave 3), 2016 (Wave 4), 2018 (Wave 5) and again in 2020 as part of TILDA's COVID-19 Study. Hierarchical mixed effects logistic regression models were applied to investigate the association between cortisol levels and clinically significant depressive symptoms before and during the COVID-19 pandemic.

RESULTS

In a full covariate adjusted model there was a significant interaction between cortisol and wave on depressive symptoms (χ2 = 8.5, p = .03). Cortisol was positively and significantly associated with elevated depressive symptoms during the COVID-19 Study (OR =1.3, 95% CI 1.11, 1.56, p = .003), and was associated with an increased likelihood of reporting clinically significant depressive symptoms during first year of the COVID-19 pandemic, when compared with before, OR = 1.4, 95% CI 1.05, 1.9, p = .015. There was no evidence of effect modification by sex.

CONCLUSIONS

Higher hair cortisol, assessed 6 years previously, predicted clinically significant depressive symptoms among middle-aged and older adults during (but not before) the pandemic. Findings suggest a biological phenotype which denotes increased susceptibility to the negative impact of environmental stress on psychological health.

COVID-19 pandemic partnership between medical students and isolated elders improves student understanding of older adults' lived experience

BACKGROUND

Evidence supports loneliness and social isolation as a strong risk factor for poor mental and physical health outcomes for older adults. The COVID-19 pandemic necessitated older adults isolate themselves for a prolonged duration. The Faculty of Medicine at the University of Toronto established the Student-Senior Isolation Prevention Partnership (SSIPP), a volunteer program involving telephone calls between medical students and older adults.

METHODS

A mixed methods pre-post study design included collecting quantitative data from older adults using the UCLA Loneliness Scale and the Warwick-Edinburgh Mental Well-being Scale. The study included 29 medical students and 47 older adults. The medical students filled out a questionnaire on self-perceived knowledge of social isolation, perception of seniors, attitudes towards seniors, and likelihood to engage in specialties focusing on older adults. Interviews were conducted with both the older adults and the medical students to understand each groups' experiences and perspectives with taking part in the SSIPP program.

RESULTS

Participation in the program resulted in significant changes for medical students in areas such as increasing their likelihood to engage in care for older adults (p < .001), improving their knowledge of social isolation for seniors (p < .001), and the value of addressing social isolation in older adults (p < .001). The interviews conducted with the medical students support these findings and provide insight into contributing factors. Loneliness and mental well-being scales did not show significant changes for older adults however, our interviews revealed they considered the program to be valuable.

CONCLUSIONS

Our results showed that after the communication outreach program, medical students' perceptions were positively influenced towards older adults and they were more likely to pursue a career concentrated on older adults. The qualitative analysis revealed older adults valued the program. Timing and consistency of calls were factors identified by this group as having practical importance.

An exploration of the consequences of, and coping with loneliness in an ageing intellectual disability population

Background: Loneliness has been associated with increased hypervigilance and sad passivity. The physiological and psychological reactions of people with an intellectual disability to loneliness have never been investigated. Therefore, this research aims to explore the outcomes of loneliness for an ageing intellectual disability population. Methods: In Ireland, data from a nationally representative data set of people aged over 40 years with an intellectual disability (N=317) was applied to a social environment model that describes the effects of loneliness in five pre-disease pathways which are: health behaviours, exposure to stressful life events, coping, health and recuperation. The data was tested through chi-squared, ANCOVA and binary logistic regression. Results: Being lonely predicted raised systolic blood pressure (A.O.R=2.051, p=0.039), sleeping difficulties (AOR=2.526, p=0.002) and confiding in staff (AOR=0.464 p=0.008). Additionally, participants who did 10 to 20 minutes of exercise daily (moderate activity) had significantly higher loneliness scores than those who did not (F=4.171, p<0.05). Conclusions: The analysis supports the concept of hypervigilance in older people with an intellectual disability but finds that the health behaviours of the lonely do not differ from the not lonely. Future research needs to investigate the longitudinal relationships between loneliness and health

Loneliness as a risk factor for cancer-related cognitive impairment: a secondary data analysis from the Haze study

PURPOSE

The purpose of this study was to investigate the association between loneliness and cancer-related cognitive impairment (CRCI) in a cohort of breast cancer survivors.

METHODS

Female breast cancer survivors (stage I-III) reporting cognitive impairments 2 months to 5 years after chemotherapy (n = 61) participated in a prospective, nonblinded, waitlist-controlled pilot study. The intervention was a tailored cognitive rehabilitation program. Data were collected pre-/post-intervention. Loneliness was measured using the UCLA Loneliness Scale. Perceived cognitive function was measured using two subscales of the FACT-Cog and two PROMIS - Applied Cognition short forms. Spearman correlation coefficients were calculated to determine the relationship between loneliness and perceived cognitive function (PCF).

RESULTS

Participants' loneliness severity was correlated with diminished PCF across all cognitive measures (Spearman r= -0.63 FACT-Cog Perceived Cognitive Impairment, p < 0.0001; r= -0.6 FACT-Cog Perceived Cognitive Abilities, p < 0.0001; r= -0.49 PROMIS Cognitive Ability, p = 0.0002; r = 0.50 PROMIS General Concerns, p = 0.0002). Loneliness scores significantly decreased following participation in the cognitive rehabilitation program in intervention participants as compared to wait-list controls [-5.0 ± 7.24, 95% CI (-8.06, -1.94), p = 0.0025].

CONCLUSIONS

Perceived loneliness was significantly and consistently correlated with PCF. The intervention may have served a dual purpose in both addressing cognitive deficits and loneliness. Additional research dedicated to understanding the association between loneliness and cognitive function, as well as screening for and addressing loneliness in clinical oncology settings, may be warranted. IMPLICATIONS FOR REHABILITATIONScreening for and addressing loneliness in oncology rehabilitation settings is warranted.Rehabilitation professionals are well-positioned to screen for and address loneliness during clinic visits as part of routine cancer rehabilitation care.Group settings may be appropriate for addressing cancer-related cognitive impairment in rehabilitation, as these groups may serve the dual purpose of addressing cognitive impairment and loneliness simultaneously.

Associations of face-to-face and non-face-to-face social isolation with all-cause and cause-specific mortality: 13-year follow-up of the Guangzhou Biobank Cohort study

BACKGROUND

Although social isolation has been associated with a higher mortality risk, little is known about the potential different impacts of face-to-face and non-face-to-face isolation on mortality. We examined the prospective associations of four types of social isolation, including face-to-face isolation with co-inhabitants and non-co-inhabitants, non-face-to-face isolation, and club/organization isolation, with all-cause and cause-specific mortality separately.

METHODS

This prospective cohort study included 30,430 adults in Guangzhou Biobank Cohort Study (GBCS), who were recruited during 2003-2008 and followed up till Dec 2019.

RESULTS

During an average of 13.2 years of follow-up, 4933 deaths occurred during 396,466 person-years. Participants who lived alone had higher risks of all-cause (adjusted hazard ratio (AHR) 1.24; 95% confidence interval (CI) 1.04-1.49) and cardiovascular disease (CVD) (1.61; 1.20-2.03) mortality than those who had ≥ 3 co-habitant contact after adjustment for thirteen potential confounders. Compared with those who had ≥ 1 time/month non-co-inhabitant contact, those without such contact had higher risks of all-cause (1.60; 1.20-2.00) and CVD (1.91; 1.20-2.62) mortality. The corresponding AHR (95% CI) in participants without telephone/mail contact were 1.27 (1.14-1.42) for all-cause, 1.30 (1.08-1.56) for CVD, and 1.37 (1.12-1.67) for other-cause mortality. However, no association of club/organization contact with the above mortality and no association of all four types of isolation with cancer mortality were found.

CONCLUSIONS

In this cohort study, face-to-face and non-face-to-face isolation were both positively associated with all-cause, CVD-, and other-cause (but not cancer) mortality. Our finding suggests a need to promote non-face-to-face contact among middle-aged and older adults.

The Lonely Brain - Associations Between Social Isolation and (Cerebro-) Vascular Disease From the Perspective of Social Neuroscience

The current COVID-19 pandemic led to a considerable reduction in in-person social contacts all over the world. In most individuals, reduced social contacts lead to the perception of social isolation causing feelings of loneliness, which are experienced as stressful. Experiencing social distress due to actual or perceived social isolation has been associated with negative health outcomes such as depression, (cerebro-) vascular disease and mortality. Concrete mechanisms behind this association are still a matter of debate. A group of researchers around Hugo Critchley with special contributions of Sarah Garfinkel and Lisa Quadt proposes a framework for the underlying brain-body interactions including elements from models of social homeostasis and interoceptive predictive processing that provides important insights and testable pathways. While in a previous publication, we reviewed literature on the observed association between social isolation and stroke and coronary heart disease, we now extent this review by presenting a comprehensive model to explain underlying pathomechanisms from the perspective of social neuroscience. Further, we discuss how neurodivergent people, e.g. autistic individuals or persons with attention deficit disorders, might differ in these pathomechanisms and why they are especially vulnerable to social isolation. Finally, we discuss clinical implications for the prevention and therapy of (cerebro-) vascular diseases.

Self-care deficit among older men in the COVID-19 pandemic: implications for nursing

ABSTRACT Objectives: to analyze self-care deficit among older men in the COVID-19 pandemic in Brazil and to discuss the implications for nursing practice. Methods: web survey, multicentric, qualitative. A total of 120 older men participated, applying a form from April to June 2020 and April to August 2021. Reflective Thematic Analysis, interpreted by Orem’s Self-Care Deficit Theory, was used. Results: temporally, the self-care of older men was manifested in the self-care requirements - affective bonds, self-care for development - meditation and self-care with health deviations - remote consultations. Fully, partially compensatory, educational/support systems mobilized self-care. Final Considerations: as care managers, nurses can strengthen the support network for older men by activating professionals from the multidisciplinary team, family members, caregivers and the community to promote self-care and correct health deviations in times of crisis.

Loneliness, social isolation, and all-cause mortality in the United States

Social isolation and loneliness are both established risk factors for mortality, but it remains unclear how these two conditions interact with each other. We used data from 3975 adults aged 25-74 years who completed self-administered questionnaires (SAQs) for the Midlife in the United States (MIDUS) National Study Wave 2 (2004-2006). Loneliness was measured by asking participants how often they felt lonely. A shortened version of the Berkman-Syme Social Network Index that captured partnerships, friends/family, religious participation, and other forms of social connection was used to assess social isolation. Follow-up for all-cause mortality was censored at the end of 2016. We used progressively adjusted Cox proportional hazard models to examine the mortality risks of loneliness, social isolation, the components of social isolation, and combinations of loneliness and isolation. We adjusted for sociodemographic characteristics in our first models and then added health behaviors and physical and mental health conditions in subsequent models. In the minimally adjusted model, loneliness was associated with higher mortality risk (HR, 1.34; 95% CI, 1.22-1.47), but the association was not significant in the fully adjusted model. Social isolation was significantly associated with mortality in the minimally adjusted model (HR, 1.24; 95% CI, 1.15-1.34) and the fully adjusted model (HR, 1.13; 95% CI, 1.04-1.23). Having infrequent contact with family or friends was the component of isolation that had the strongest association with mortality. Contrary to prior literature, which has found either no interaction or a synergistic interaction between isolation and loneliness, we identified a significant, negative interaction between the two measures, indicating that loneliness and social isolation may partially substitute for one another as risk factors for mortality. Both are associated with a similar increased risk of mortality relative to those who express neither; we find no evidence that the combined effect is worse than experiencing either by itself.

Association of Social Isolation With Disability Burden and 1-Year Mortality Among Older Adults With Critical Illness

Importance

Disability and mortality are common among older adults with critical illness. Older adults who are socially isolated may be more vulnerable to adverse outcomes for various reasons, including fewer supports to access services needed for optimal recovery; however, whether social isolation is associated with post-intensive care unit (ICU) disability and mortality is not known.

Objectives

To evaluate whether social isolation is associated with disability and with 1-year mortality after critical illness.

Design, Setting, and Participants

This observational cohort study included community-dwelling older adults who participated in the National Health and Aging Trends Study (NHATS) from May 2011 through November 2018. Hospitalization data were collected through 2017 and interview data through 2018. Data analysis was conducted from February 2020 through February 2021. The mortality sample included 997 ICU admissions of 1 day or longer, which represented 5 705 675 survey-weighted ICU hospitalizations. Of these, 648 ICU stays, representing 3 821 611 ICU hospitalizations, were eligible for the primary outcome of post-ICU disability.

Exposures

Social isolation from the NHATS survey response in the year most closely preceding ICU admission, which was assessed using a validated measure of social connectedness with partners, families, and friends as well as participation in valued life activities (range 0-6; higher scores indicate more isolation).

Main Outcomes and Measures

The primary outcome was the count of disability assessed during the first interview following hospital discharge. The secondary outcome was time to death within 1 year of hospital admission.

Results

A total of 997 participants were in the mortality cohort (511 women [51%]; 45 Hispanic [5%], 682 non-Hispanic White [69%], and 228 non-Hispanic Black individuals [23%]) and 648 in the disability cohort (331 women [51%]; 29 Hispanic [5%], 457 non-Hispanic White [71%], and 134 non-Hispanic Black individuals [21%]). The median (interquartile range [IQR]) age was 81 (75.5-86.0) years (range, 66-102 years), the median (IQR) preadmission disability count was 0 (0-1), and the median (IQR) social isolation score was 3 (2-4). After adjustment for demographic characteristics and illness severity, each 1-point increase in the social isolation score (from 0-6) was associated with a 7% greater disability count (adjusted rate ratio, 1.07; 95% CI, 1.01-1.15) and a 14% increase in 1-year mortality risk (adjusted hazard ratio, 1.14; 95% CI, 1.03-1.25).

Conclusions and Relevance

In this cohort study, social isolation before an ICU hospitalization was associated with greater disability burden and higher mortality in the year following critical illness. The study findings suggest a need to develop social isolation screening and intervention frameworks for older adults with critical illness.
